Firms from transforming economies can leverage the characteristics of their location to develop innovative business models before internationalizing. This note showcases ByteDance's innovative business model for its TikTok app, which became one of the most downloaded apps globally. ByteDance used its large and increasingly demanding home market to experiment with creative combinations of business model elements to develop a unique business proposition that positions the TikTok app as a hybrid of social networking and video-sharing. In addition, TikTok benefitted from China's IT strength supported by national high-tech policy to an AI-based recommendation algorithm as a non-location bound resource. TikTok shows that firms from transforming economies can launch successful global products through business model innovation.
A metal−organic framework (MOF) [Cu(PDA)-(DMF)] was synthesized under mild mixed solvothermal conditions. It is constructed by 1,10-phenanthroline-2,9-dicarboxylic acid (H 2 PDA) and Cu 2+ ions. The complex exhibits high peroxidase-like activity and can catalytically oxidize the colorless substrate 3,3′,5,5′tetramethylbenzidine to a blue product in the presence of H 2 O 2 . However, the peroxidase-like activity of [Cu(PDA)(DMF)] can be potently inhibited in the presence of dopamine. Based on this phenomenon, the colorimetric detection of dopamine was demonstrated with good selectivity and high sensitivity. [Cu(PDA)(DMF)] showed good stability and robust catalytic activity, which has been employed in the detection of dopamine in human urine and pharmaceutical samples.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
